Cryptographic DoS Amplification in Hybrid Post-Quantum Deployments: Adversarial Algorithm Substitution and Its Countermeasures
The Cryptographic Amplification Factor (CAF) is defined, a metric for the per-resource cost asymmetry that an adversary induces by forcing a TLS 1.3 server onto a high-cost signature algorithm (SLH-DSA instead of a low-cost one (ECDSA or ML-DSA) instead of a low-cost one (ECDSA or ML-DSA).
